Router Additional

[Challenge 1]. This challenge involves the configuration of SIP with a Cisco SIP Gateway FXO setup. Some routers have Foreign Exchange Station (FXS) interfaces which can connect to a standard telephone, fax machine, or similar device and thus must provide ringing, voltage supplies, and a dial tone. Normally the FXS interface uses an RJ-11 connector to connect to telephone equipment.

[Challenge 2]. This challenge involves the configuration of DLSw (Data-Link Switching), which allows the tunneling of Systems Network Architecture (SNA) and NetBIOS traffic within an IP network. It uses a switch-to-switch protocol, and the routers are named data link switches.

[Challenge 3]. This challenge involves the configuration of a frame-relay switch.

[Challenge 4]. This challenge involves the configuration of a sub-interface on a frame-relay connection for a point-to-point link.

[Challenge 5]. This challenge involves the configuration of Voice over Frame-relay (VoFR).

[Challenge 6]. This challenge involves the configuration of a sub-interface on a frame-relay connection for a multpoint link (that is, a connection to more than one frame relay connection).

[Challenge 7]. This challenge involves the configuration of the ATM interface using a sub-interface. This is the latest method of defining the PVC.

[Challenge 8]. This challenge involves advertising an interface so that only the next router can find a route to it. For this an offset of 14 is added to a local interface, so that the next router will have a metric of 15, and then devices next to this will have a Not Available (as a hop count of 16 with RIP means infinity).

[Challenge 9]. This challenge involves converting an RIP multicast into a unicast to a specific address. Normally RIP table are sent through a multicast address of 224.0.0. on UDP port 520.

[Challenge 10]. This challenge involves creating a distribution-list, which does not send routing updates on a specific network range.

[Challenge 11]. This challenge involves creating a rate-limit for QoS.

[Challenge 12]. This challenge involves defining Local-area Mobility (LAM), which a router to listen to foreign ARPs, and add them to its routing table, which can then be sent to neighhouring devices. It thus supports mobility of hosts to different subnets, which still keeping the same IP address.

[Challenge 13]. This challenge involves defining Local-area Mobility (LAM), which a router to listen to foreign ARPs, and add them to its routing table, which can then be sent to neighhouring devices. It thus supports mobility of hosts to different subnets, which still keeping the same IP address. It uses an ACL to define the range of hosts to be used for LAM.

[Challenge 14]. This challenge involves defining a high priority for IP traffic but a medium priority for DLSw on a given interface (E0). It is used to define QoS, and focuses on CCIE certification.

[Challenge 15]. This challenge involves the definition of a time-range, which can be applied to an access-control list.

[Challenge 16]. Gateway Load Balancing Protocol (GLBP) in the same way as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) provides an alternative route for network traffic from a failed router or circuit. It also supports load sharing between a group of redundant routers. This challenge involves the configuration of GLBP.

[Challenge 17]. Virtual Router Redundancy Protocol (VRRP) in the same way as Hot Standby Router Protocol (HSRP) and Gateway Load Balancing Protocol (GLBP). It provides an alternative route for network traffic from a failed router or circuit.. This challenge involves the configuration of VRRF.
